LC - Uncorrectable Errors I/O Error!

Recommended Posts

I am using quality BD discs (Quantum Optical), and have never had an issue until recently. I though my burner was going bad, so I ordered a new one - but the errors continue (this is on VERIFY, not burn!)

I/O Error!

ASC/ASCQ Interpretation: L-EC Uncorrectable Error

It's getting ridiculous and wasting me a LOT of money. Please help!

Could this be the SATA cable?

I had a BD50 blow out at 99%!!!

=====================================

I just checked the file that didn't verify and it played perfectly fine. WTH is going on???!!!!

*I should add that the SATA cable is a Monoprice cable, so not a no-name brand.

**I have also tried with OPC on and off - it doesn't seem to make a difference. Win10x64 current Insider build.

Here are several failed log entries - the first few have OPC enabled, the last one does not. I have not seen a difference in having it enabled vs not enabled. These logs are all using a brand new ASUS BW-16D1HT. My prior drive was an LG WH16NS40 - when I started b\getting the failures, I thought it might be that the drive was dying (had that happen before with DVD-RW drives, but the LG was my first BD-R drive). I have also tried BD-R Verify Not Required on and off, with no apparent difference. I've no idea how to switch Hardware Defect Management Active to Yes, or even what it does, or if it is necessary/advisable. You can see that I manually selected Retry several times (I've occasionally found success with that, but not in these cases).

Did you get failed burns on the LG, too? I couldn't quite tell if you had said that or not.

You've used 2 different types of discs, the Quantum and Ritek. Ritek is a known problem maker. I've never had Quantum kind so I can't say. Were you getting success with Quantums before? If this is your first time using Quantum, maybe they aren't quality blanks after all. Or your drive doesn't like them.

Now, I can tell you from trying 2 different units of the BW-16D1HT, that ASUS drive is trash. It destroys rewritable media so I can't see that it's any good at writing, well, anything. Which is why I asked if you were also getting failures on the LG, too. If you were getting failures on both drives, the only thing I would try next is trying a known quality BD-R like Verbatim's VERBAT-IM kind. If you get failures on those, then you know it's not down to the drives as you get failures on both drives and on 3 different kinds of media. So, the issue must be something else. Either a hardware problem or a Windows configuration error of some kind.

The Asus was recently rated as the best, most durable drive, which is why I got it over another LG. And yes, I got the VAST majority of the failures with the LG - I thought the LG might be dying, that's why I got the Asus. The Ritek discs are the BD50s and I only had one of those blow out - the one that had the error at 99% I tested and it played fine - it was the 12 BD25s of OTCBDR-002-000 that I had the issue with. I'm wondering if it was just a bad batch of discs. I've never had a problem with either before (on the LG) - maybe 1 or 2 discs, but that's it.

My experience with ASUS has been iffy. The first ASUS I had was an external model which passed all tests I threw at it, but now that I have to use it as my primary drive, it sometimes only writes at 4x to 8x rated DVD+R DL. Given my success with this ASUS, I tried your ASUS twice and it failed miserably. It destroys Ritek 8x DVD+RW and Verbatim BD-RE DL. I thought maybe I got a bad unit initially so I tried another and got the same results. With those catastrophic failures, I simply returned that ASUS and wrote it off as trash.

I still prefer my Pioneer BDR-2209 over anything else. Once I can find a decent enough USB enclosure that doesn't drop communication like the last one I got. Since Dell removed the half height bays from their PC's, forcing you to choose junk slim models. Which I won't do. I got one in my new Dell and it's already revealed what I've learned from users on this forum about slim drives.

It's always possible you got a bad batch of discs if you've used them before with no problem. However, that's generally unlikely. What is more likely is that Quantum changed the manufacturing process, if they did that, so they're not the same kind of discs they used to produce. Without failures on discs I know I are good, the Verbatim VERBAT-IM discs, I couldn't say if it's the discs you're using or not.
